Domain Sponsors Pro (DSP) is the ultimate domain traffic monetization software which allows you to operate a business just like DomainSpa.com. DSP enables you to operate a traffic exchange service which allows domain name owners to maximize revenues from domain traffic by displaying advertiser's PPC search engines, affiliate programs or targeted ad copy on their domain names. It comes with a built-in domain owner and advertiser membership system integrated with Paypal and 2checkout so you can receive funds from advertisers and send money to domain owners.
